GAS-RANGE BURNER.

Application led March 29, 1924. Serial No. 702,734.

This invention relates to an improvement in gas rangel'uirners in which the primary object thereof is to provide an improved combined broiler and oven burner.

Another object of the invention is in providing a gas burner with improved means whereby the flames ot the burning gas from the burner will be directed both upwardly and downwardly, the upwardly directing llames acting more directly upon the oven of the gas range, whereas the downwardly directing flames willv act more directly upon the lower arranged broiler oven of the gas raiigel A turtherobiect of the invention is in disposing portions ottlie gas burner in positions peculiar to` the upwardly extending heat tlues of the oven.

A still further object of the invention is in providingV an improved form f oven bottom having a co-operable relation with this improved burner.

Other and furtherV objects will appear in the specification and be specifically pointed out in the appended claims', reference being lia-d' tothe accompanying drawings, exempli tying the'invention, and in which Figure 1 is a horizontal section taken through the oven of a gas range showing tliis'ii'nproved gas burner and oven bottom mounted in operable relationtliereto. Figure 2 is a vertical section taken on the li'ne IIII of Fig. 1`.

Figure 3 is a fragmentary horizontal section taken through a portion ot this improved burner.

Figure 4 is a tra.Qmentaryl vertical section taken" onthe line .IV- IV oi Fig. 1.

Referring by numerals tothe accompanyingdrawings', 1 designates the side walls of a gas-range'. oven, 2 the end wall and 3 the front wall or oven door. said walls providing the oven/l. y

Horizontally disposed within the ovend is a removable oven'bottom 5, said bottom 5 being supported at its inner end on the bracket' or ledge 6 which secured to the end wall 2, the 'forward end of the bottom being supported upon' the'b'raclets such as ,7. The oven bottom 5 is provided'on each side with au upturned flange 8, and for' reinforcing each ot said vflanges is a stiffening-- member 9. each being secured to a respective flange by the bolts 10. I Each ot the stiftening .members 9 is provided' with a toot 11 at each en'd' which rests upon the bottom proper of the oven bottom 5 as' shown in Fins. 1 and 3. rranged beneath the oven bottom istlie improved' burner 12, said burner being comprised ot av pair of spaced apart longitudinally extendinghollow legs 13 which are closed at each end and joining said legs is a pair of transversely disposed spaced apart hollow legs 14, said legs 14 being arra'i'iged intermediate of the length of the legs 13. Communicating with one of the hollow legs 13 is a gas supply neck 15, said neckV engaging with the said leg 13 midway of its length as shown in Fig. 1.

The burner 12 is supported position beneath the oven bottom 5'by a pair of transversely disposed rods 16 which ares'upportefd at their ends in brackets 17 which are s'ecuredito respective side walls 1, each of lsaid rods engaging beneath the hollow legs`13 of the burner and are ldisposed between respective depending" lugs 18 which areform'ed in the under side of said hollow legs 13.

Secured 'to each of the in ner` liiiings 1 91 to the side walls 1 are a series othorizoiitally disposed ledges 20, said ledges beingdis posed on a plane beneath the burner l2'a`n'd are tor the purpose ot supporting the broiler pan 21 in a selective position.

Arranged above the oven bottom and in vertical alinement with each of the stiffeiiing members 9 oit' said bottom is `an inner wall 22 each bearing a series of .shelf ledges 23 for the reception oi a removable oven shelf not shown. The lower extremity of each inner wall 22 is held' a. -di stance ab0ve each ol" the stitfening members 9 thereby providing a passageway 24 beneath each of the walls 22 which provides communication above they bottom oven 5 for the products of combustion thereabove. Eachkv of the inner walls 22 is disposed a distance inwardly from the lining 19 thereby providving vertical extending. lues 25 which lead to the top of the oven.

The hollow legs 13. ot the burner 12 are each provided with a series of outlet openings 26 which are arranged so as tok direct the flame ot the burning gas upwardly and voutwardly in the directionas indicated by the arrows 27 in Fig. 2. It is to be noted that each of the legs 13 vis arranged adjacent a respective side of the oven bottom 5 so that the gas flame will engage the oven bottom adjacent respective sides wherein the flames will be deflected from the bottom and directly into respective vertical [lues 25. This is for the purpose of directing most of the heat units upwardly as against heretofore directing of the heat units against. the oven bottoni centrally thereof thereby eliminating the warping of the oven bottom on account of the gas flames not permitted to traverse the entire oyen bottom.

The hollow lees 14 of the burner are each provided with a row of inwardly and downwardly directing gas emitting openings 28 which are adapted to direct the gas burning flames towards the broiler pan 21 in. the direction of the arrow 29.

So that a uniform amount of gas will be provided to all of the hollow legs 13 and 14 of the burner, improved means are provided within the burner, said means being comprised of a centrally disposed deflecting portion 30 which is arranged to receive and divide the gas from the supply neck 15 to respective oppositely disposed portion 13a of one of the hollow legs 13. An extending lip 31 is projected within each of the passageways of the portions 13n from a respective hollow member 14, each of said lips 31 directing the gas into each respective hollow member 14 and formed in the other hollow member 13 is a pair of deflecting portions 32 each being arranged in alinement with the discharging end of a respective hollow leg 14 and are adapted to direct the gas to the last mentioned hollow leg 13 and to the extending portions 13b thereof.

In the operation of a gas range burner of this improved character, when a gas supply is provided within the supply neck 15 of the burner 12, the deflecting portion 30 will divide the gas entrainment and cause it to be .forced into the portions 13a of one of the hollow legs 13. the gas from the hollow leg' 13 being acted upon by thel respective deflecting portions 31 in which a zgas entrainment will be forced in to each of the transversely disposed hollow legs 14 and as the `gras reaches the end of each of the hollow legs 14, the deflectine portions 32 will divide the entraining gas as it leaves each of the hollow lefrs 14 and force the gas into the other hollow leg 13 and into the extremities 13" thereof.

The eas supply emitting from the burner upon being ignited will. produce flames which are directed both upwardly and downwardly. the upwardly directing flames beine` provided by the upwardly and outwardly discharging' openings 26 which are provided .in the pair of hollow legs 13, the Ias flames from said openings after engaging the oven bottom 5 adjacent the side edres thereof being immediately deflected off the oven bottom on account of the angular ar 'angement of the discharge openines 26`r the flames after beingddellected off the oven bottom entering directly into respective vertical flues 25 which lead upwardly to the top of the oven and are de- .llected by the oven lop not shown, bach into the oyen above the oren bottom 5.

Owing; to the llames from the hollow legs 13 engagingT only the outer portions of the oven bottom 5. said portions of the oven are relieved of warping on account of the upwardly bent flanges 8 being reinforced by the reinforcing' members 9 and furthermore7 on account of the flames from the hollow members 13 engaging only the outer portions of each side of the oven bottom 5. said bottom is relieved of beingV subjected to the extreme heat heretofore given to oven bottoms where the burner provides the llame to the entire oven bottom which creates a burning action to food stuffs arranged thereabove in the process of baking. This improved manner of allowingf only the outer portion of the oven bottom to be engaged by the `as llames and afterwards immediately directing the llames and heat therefrom upwardly into the vertical flues 25 creates more of a uniform heat throughout the oven.

Flames created by the burning of the iras as it is emitted from the downwardly and inwardly directing openings 28 of the transverseI hollow lees 14 will cause the heat to be directed downwardly towards the broiler pan 21 arranged below the burner 12. said llames not only beingr prevented from en- .earring the central portion of the oven bottom 5 but in addition thereto directing the flames and consequent heat therefrom to wards the broiler pan where it is most desired. After the heat units have become nonfused above the broiler they will ascend upwardly in the flues 25 and become effective in the oyen 4.

From the aforesaid description of this improved invention. it is obvious that a gas rane'e of great efficiency is provided.

What we claim isz-- 1. A gas burner for a. range comprising ay pair of spaced apart paralleline' hollow lees each having a row of upwardly inclined discharge openings. each of said rows of openings beiner inclined outwardly from each other. and a pair of transversely disposed hollow legs ioiningr with said other pair of hollow legs each beine` provided with a row of downwardly and inwardly directinsr discharge openings.
